why css does not apply when complete url is entered home/index
Why is stylesheet only working for the index page, but not for any extensions of the index page?
Why css does not apply when complete url is entered like home/index
You're using a relative URL for the stylesheet; you need to prepend a forward slash so that it's relative to the root and not the page being viewed.
<link rel="stylesheet" type="text/css" href="/static/style.css" />
